Vietnamese commercial bank USD selling rates fell below VND 26,000 for the first time in about 18 months on October 30, with Vietcombank down VND 60 over the week. The free-market dollar also dropped more than VND 400 in one session, while the State Bank of Vietnam central rate stood at VND 25,637.
